Structuring construction for an aircraft fuselage
View Patent ↗A structuring construction for an aircraft fuselage is provided having an outer skin as well as a plurality of formers extending at a spacing side by side crosswise to the longitudinal direction of the fuselage wherein at least a partial number of the formers include a main former portion which is channel-like in cross section and the channel edges of which are adjacent to the outer skin and wherein the channel space of the main former portion serves to accommodate at least one supply air line which may be formed, for example, by a separate pipe line.
1. Structuring construction for an aircraft fuselage of an aircraft, comprising:
an outer skin; and
a plurality of formers extending at a spacing side by side crosswise to the longitudinal direction of the fuselage, wherein at least a partial number of the formers include a main former portion formed as a channel in cross section, channel edges of which are adjacent to the outer skin,
wherein at least one air line forming a riser of an air conditioning system of the aircraft and serving to convey supply air to an aircraft cabin of the aircraft is disposed or formed in a space between the main former portion and the outer skin at least in the formers constructed as the main former portions.
2. Structuring construction according to claim 1 , wherein the air line is formed by a separate pipe line.
3. Structuring construction according to claim 2 , wherein an at least thermally insulating material arrangement is disposed between the former and the air pipe line.
4. Structuring construction according to claim 2 , wherein the air pipe line lies against the former, at least in parts.
5. Structuring construction according to claim 2 , wherein the air pipe line is adapted in cross section at least to the path of a contour of channel side flanks or/and of a channel bottom of the main former portion.
6. Structuring construction according to claim 1 , wherein the air line is defined at least in part by the former.
7. Structuring construction according to claim 1 , wherein an at least thermally insulating material arrangement is disposed between the outer skin and the air line.
8. Structuring construction according to any one of claim 1 , wherein at least one stringer extending in the longitudinal direction of the fuselage passes through apertures in two channel side flanks of the main former portion and crosses the air line without contact.
9. Structuring construction according to claim 1 , wherein at least the main former portion is made of a carbon fibre-reinforced plastics material or is coated with a carbon fibre-reinforced plastics material, at least in regions.
10. Structuring construction according to any one of claims 1 to 9 , wherein the main former portion has a cross-sectional shape which is U-shape, V- shaped, semicircular, trapezoidal, or rectangular.
11. Structuring construction according to claim 1 , wherein fastening portions directed away from one another are disposed at the channel edges of the main former portion to fasten the former to the outer skin.
12. Structuring construction according to claim 1 , wherein the main former portion comprises a bottom wall and two mutually opposite side walls, joined to a bottom wall, like a U-shape in cross section.
13. Structuring construction according to claim 1 , wherein at least one opening, bordered on all sides, is formed in at least one wall of the main former portion.
14. Structuring construction according to claim 1 , wherein at least the main former portion is coated in regions with a carbon fibre-reinforced plastics material.
15. Structuring construction according to claim 1 , wherein the main former portion includes two walls which extend at a spacing from one another to form channel side flanks joined to the outer skin.
